Waste material compactor

Abstract

A waste material compaction device includes an auger cone having a base skirt; a hopper for containing said auger cone; a support located inside the auger cone and fitted to the hopper; an auger flight arranged on an outer surface of the auger cone; a first bearing located adjacent the base skirt of the auger cone; a second bearing positioned inside the auger cone at a distance from the first bearing; and an electric motor and a gearbox for driving the auger cone and the auger flight such that waste material placed in the hopper is compacted in a predetermined direction; the first and second bearings bearing a working load of the waste material compaction device.

What is claimed is: 
     
       1. A waste material compaction device comprising:
 an auger cone having a base skirt; 
 a hopper for containing said auger cone; 
 a support located inside aid auger cone and fitted to said hopper; 
 an auger flight arranged on an outer surface of said auger cone; 
 a first bearing located adjacent said base skirt of said auger cone; 
 a second bearing positioned inside said auger cone at a distance from said first bearing; and 
 an electric motor and a gearbox for driving said auger cone and said auger flight such that waste material placed in said hopper is compacted in a predetermined direction; 
 said first and second bearings bearing a working load of the waste material compaction device. 
 
     
     
       2. The waste material compaction device according to  claim 1 , wherein said second bearing is located inside said auger cone at two-thirds of an overall length of said auger cone away from said base skirt of said auger cone. 
     
     
       3. The waste material compaction device according to  claim 2 , wherein said support is a mounting cone. 
     
     
       4. The waste material compaction device according to  claim 3 , wherein said auger cone has a taper with respect to a central axis of said auger cone, said taper of said auger cone preventing the waste material binding and jamming within said hopper. 
     
     
       5. The waste material compaction device according to  claim 2 , wherein said auger cone has a taper with respect to a central axis of said auger cone, said taper of said auger cone preventing the waste material binding and jamming within said hopper. 
     
     
       6. The waste material compaction device according to  claim 1 , wherein said support is a mounting cone. 
     
     
       7. The waste material compaction device according to  claim 6 , wherein said auger cone has a taper with respect to a central axis of said auger cone, said taper of said auger cone preventing the waste material binding and jamming within said hopper. 
     
     
       8. The waste material compaction device according to  claim 1 , wherein said auger cone has a taper with respect to a central axis of said auger cone, said taper of said auger cone preventing the waste material binding and jamming within said hopper. 
     
     
       9. The waste material compaction device according to  claim 8 , wherein said taper of said auger cone, with respect to said central axis of said auger cone is in a range from 1 to 10 degrees. 
     
     
       10. The waste material compaction device according to  claim 9 , further comprising:
 a receiver; 
 said auger flight having a taper at a divergent angle to said taper of said auger cone, the divergence between said auger flight and said auger cone assisting the compaction of the waste material being placed into said hopper and assisting the driving of the waste material in said predetermined direction into said receiver; 
 said receiver being separate from said hopper. 
 
     
     
       11. The waste material compaction device according to  claim 10 , wherein said central axis of said auger cone aligns with a center of an end face of said hopper at said base skirt of said auger cone; and aligns with an aperture in a wall of said receiver. 
     
     
       12. The waste material compaction device according to  claim 8 , further comprising:
 a receiver; 
 said auger flight having a taper at a divergent angle to said taper of said auger cone, the divergence between said auger flight and said auger cone assisting the compaction of the waste material being placed into said hopper and assisting the driving of the waste material in said predetermined direction into said receiver; 
 said receiver being separate from said hopper. 
 
     
     
       13. The waste material compaction device according to  claim 12 , wherein said central axis of said auger cone aligns with a center of an end face of said hopper at said base skirt of said auger cone and aligns with an aperture in a wall of said receiver. 
     
     
       14. The waste material compaction device according to  claim 1 , wherein said support is configured to conform to a shape of said auger cone. 
     
     
       15. The waste material compaction device according to  claim 1 , wherein said gearbox includes an outward shaft, said outward shaft being located adjacent to said second bearing. 
     
     
       16. The waste material compaction device according to  claim 1 , wherein said gearbox is located within said support. 
     
     
       17. The waste material compaction device according to  claim 1 , wherein said support is a mounting cone. 
     
     
       18. The waste material compaction device according to  claim 17 , wherein said mounting cone has a truncated shape. 
     
     
       19. The waste material compaction device according to  claim 17 , wherein said mounting cone has a frusto-conical shape.
